IMPROVEMENT IN LATHES FOR CLOTHES-PINS.

Specification forming part of Letters Patent No. 196,353, dated October23, 1877 application filed I March 14, 1877.

To all whom it may concern:

. Be it known that I, AARON HALL, Jr., of

St. Johnsville, in the county of Montgomery and State of New York, haveinvented a Lathe for OlothesPins, &c., of which the following is aspecification:

This invention relates to improvements in lathes for turningclothes-pins; and consistsin the construction and arrangement of thevarious parts of such machine, as hereinafter described and claimed.

To enable others skilled in the art to fully understand and construct mylathe, I will proceed to describe it, as follows: Figure l representsaside elevation of my invention. Fig. 2 is an isometrical view of theturning-knife. Fig. 3 is an edge view of the same, showing in dottedcircles the position of the clothes-pin or blank to be turned. Fig. 4 isa sectional view of the feed-wheel, taken in the line 00 m, Fig. 1.

The arrows indicate the direction of motion of the several parts; andsimilar letters of reference indicate corresponding parts in all thefigures.

A, Fig. 1, represents the bed-frame of the lathe. b b b b are the headstocks or frames supporting the bearings for the spindles O G. Thespindles are provided with the thrustbearings (Z d and d d, which aresecured to the rods 0 e. Cams F F are secured to the shaft G G. Saidcams actuate the spindles forward or toward each other, while thesprings h it cause the spindles to recede from each other when releasedby the cams F F in the 161811311 way, the clothes-pin being shown at 2',*ig. 1.

The intermitting rotary feed-wheels are shown in Figs. 1 and at at K.Said feed-wheels encircle the camshaft G, but do not touch itnecessarily. They have independent bearings in the retracting-plates LL, said plates or frames L L being provided with small round holes,through which the spindle-chucks can pass, but too small for theentrance of the clothes-pin ortother article to be turned.

The feed-wheel K is rotated by means of a pawl, m, and actuated by acam-or tappet, a, secured to the cam-shaft G. Said pawl engages with aratchet-wheel, 0, secured to the hub of the feed-wheels K K. Aspring-catch,

1?, drops into the circular recesses, (which also receive the blanks anddeliver the turned c1othes-pins,) as shown in Fig. 4, which retains thewheels K K at each rest in their proper positions, in order to hold theblanks, as shown at n, Fig. 4, to be centered by the spindle-chucks, aswill be readily inferred.

Just before .the feed-wheels K K are again rotated one notch thespring-catch P is raised out of the notch in said feed-wheel by means ofa cam or tappet secured to the cam-shaft Gr, actuating an angular arm,R, to which a pin, 8, is affixed, which raises the spring from thecircular recess.

It will be observed that the feed-wheels K K and ratchet 0 have acorresponding number of notches, for obvious reasons.

A gear, 1, is secured'to the cam-shaft G, which rotates a gear, t,secured to the shaft u, to which is secured a cam, (shown in dottedlines,) which oscillates the knife-frame V in the usual ,way. Theknife-frame is also hinged in the usual way to the frame of the lathe inany convenient way, in order to secure rigid oscillations. The kniferepresented in Figs. 2 and 3 at W is provided with two faces, as shownin Fig. 2 at J, or outer face, and Q the bevel or inner surface, againstwhich the revolving clothespin revolves or wears, as shown in Fig. 3;and the bevel surface is ground away and sharpened whenever the edgebecomes worn away, or becomes dull by the constant friction of therevolving clothes-pin or other article, as represented at n, Fig. 3, indotted circles. The surfaces J and Q are nearly exact counterparts ofthe clothes-pin as to sectional 0011- tour. The surface J is not changedby grinding or otherwise; but the bevel Q, is the surface that receivesthe grinding and sharpening, as has already been stated. The faces J andQ, terminate or form a junction in the edge, which is quite str ightwhen viewed from a point at right angles to the bevel face.

It will be iniderstood that the knife W is a broad or finishing knife,which turns a shaving the entire length. of the clothes-pin, in theusual way. p

I am aware of Patent No. 144,152, and here by disclaim the constructiontherein shown and described.
